Description:

This 'Engines room' ('sala motori') is a test scene for experimenting with Global Illumination , with material , lights and settings for VrayBlender .

It's a simple architectural interior , lit by daylight only .

It has relatively small windows : big enough to get the room decently lit in a sunny afternoon , but still small enough to create some technical problems for GI calculations.

The settings in this scene aren’t defaults , not much different but tuned for this scene , and in general for interior scenes that are a little “nastier” than usual : because of small , distant light sources that require lots of bounces to fill the scene with light , scenes with very localized strong reflection highlights , with a discrete amount of glossy reflections , etc..

So have a look , but keep in mind there’s a reason if the factory defaults are different (they’re the most universal) while settings in this scene are more tuned to a scene like this one.

Render time and quality : this thing renders in 30mins on a core quad 3ghz at 1080p. Quality is not extra-high , GI noise splotches are mostly gone , but still some noise in reflections. Anyway good considering render time.

The scene is setup for VrayBlender 2.5 , i'd like to adapt it for other engines (such as Cycles and Luxrender ) in the future.

If anyone is interested in doing that too , please go ahead ! and let me know of your results.

It might be interesting even just to test with a clay material.

And especially to test how much different is to setup gi with sun coming from the big windows on the left , with large areas of direct light Vs. sun coming from the small windows on the right and a weak skylight from the opposite side.

Depending on engines the 2 cases can be similar to setup or very different and have very different render times .

Scene includes packed textures (unpack to files to render with Vray) .

Also included a simple node setup for the rendered image.

Doesn't include rendered .exr layers.

Includes a materials test scene.

    Thanks!

    I made this to have a complete example of a basic/typical archviz workflow , To use in a workshop i'll hold @ Digital-media workshops on 26 oct in Torino , Italy (free , live streaming , spoken language : Italian )

    Doing this scene was also good to review / check of all the technical stuff about Vray i started to give for granted (while actually .. i discovered a few new things )

    This is the second file on Blend Swap, in two days, that doesn't render out correctly. It's missing textures and some of the textures that are present are stretched. If it's outdated then it needs to be pulled. Or at least have the textures removed and a new rendered image and description reflecting what your really getting.
